High Injury Network
A high injury network (sometimes shortened to HIN) is a way of identifying parts of an urban street network with higher rates of traffic injuries or fatalities, typically with a goal of prioritizing these streets for safety interventions. High injury networks have been published by many cities in the US and Canada as part of their efforts to work toward Vision Zero. While data on fatalities and collisions have long been available in many municipalities, the first HIN per se was published by San Francisco in 2013, though work on similar efforts had begun there as early as 2011. Creating a HIN is a data-driven exercise, and the analytic methods and data sources used may vary widely. Most HINs are created at the scale of cities A city is a human settlement of a substantial size. The term "city" has different meanings around the world and in some places the settlement can be very small. Even where the term is limited to larger settlements, there is no universally agree ... wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Street Network
A street network is a system of interconnecting lines and points (called ''edges'' and ''nodes'' in network science) that represent a system of streets or roads for a given area. A street network provides the foundation for network analysis; for example, finding the best route or creating service areas.Wade, T. and Sommer, S. eds. A to Z GIS' They greatly affect in-town movement and traffic. Street networks can become very complex in cities. Street networks are very often localized, because there is little non-highway transportation from town to town. The U.S. Highway System is like a street network, but it is national, and consists of highways instead of streets and roads.

Traffic Collision
A traffic collision, also known as a motor vehicle collision, or car crash, occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other moving or stationary obstruction, such as a tree, pole or building. Traffic collisions often result in injury, disability, death, and property damage as well as financial costs to both society and the individuals involved. Road transport is statistically the most dangerous situation people deal with on a daily basis, but casualty figures from such incidents attract less media attention than other, less frequent types of tragedy. The commonly used term car accident is increasingly falling out of favor with many government departments and organizations: the Associated Press style guide recommends caution before using the term and the National Union of Journalists advises against it in their Road Collision Reporting Guidelines. Some collisions are intentional vehicle-ramming attacks, staged crashes, vehicu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Road Safety Data Sets
A road is a thoroughfare used primarily for movement of traffic. Roads differ from streets, whose primary use is local access. They also differ from stroads, which combine the features of streets and roads. Most modern roads are paved. The words "road" and "street" are commonly considered to be interchangeable, but the distinction is important in urban design. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically, many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base ot ...
